Per-Seat Pricing for Trello Power-Ups

How much should you charge for a Trello Power-Up? If you've spent any time looking at what other developers charge, the answer is all over the place—one dollar here, fifty dollars there. But look closer and a pattern emerges. The Power-Ups that sustain real businesses tend to land between five and fifteen dollars per seat per month. That's the range where someone can put it on an expense report without asking permission, but where the maths still works for you once a team of ten or twenty is paying.

Why Per-Seat Pricing Works for Collaborative Tools

Trello is inherently collaborative. Boards exist to be shared, cards move through workflows involving multiple team members, and the value of any Power-Up grows with the number of people who use it. Per-seat pricing accounts for this naturally.

When revenue scales with users, pricing feels fair. A two-person team pays less than a twenty-person department. Nobody subsidises anyone else. This directly affects willingness to pay—teams getting proportional value are far less likely to churn than those locked into flat rates that feel punitive at small scale or like a bargain they might lose at large scale.

What the Marketplace Tells Us

Look at pricing across over 150 paid Power-Ups on the Trello marketplace and the five-to-fifteen-dollar range shows up again and again. Below five dollars, you're competing on impulse—dozens of Power-Ups price at one or two dollars per month, which can signal a throwaway project rather than a serious tool. Above $15, you start bumping into expense approval thresholds—the kind where someone needs a manager's sign-off before they can subscribe —which slows adoption considerably. The sweet spot sits between those two thresholds, where the price signals credibility without creating friction.

Within that range, where you land depends on how much heavy lifting your Power-Up does. Simpler tools that enhance what Trello already does sit at the lower end. Tools that handle entire workflows—time tracking, project management, reporting—push toward ten dollars and above.

Graduated and Volume Pricing

Flat per-seat pricing works until customers scale. A ten-person team paying $10 per seat barely notices the $100 monthly line item. A two-hundred-person department at the same rate faces twenty-four thousand dollars annually—enough to trigger procurement review and kill deals. Flat pricing can prevent you from landing your most valuable customers.

Graduated pricing solves this by reducing the per-seat cost as the number of seats increases. A Power-Up priced at ten dollars per seat might charge the full rate up to twenty-five seats, eight dollars for seats twenty-six through one hundred, and six dollars beyond that. The small team still pays ten dollars. The two-hundred-person department pays an effective rate closer to seven dollars, bringing the annual total down to around seventeen thousand, a meaningful difference in a budget conversation.

Volume pricing takes a different approach: once a customer crosses a threshold, the reduced rate applies to all seats. Crossing from twenty-five to twenty-six seats drops the entire subscription from ten to eight dollars per seat. Simpler for customers to understand, but it introduces revenue cliffs where adding a single seat can actually reduce your total income. Graduated pricing avoids this by discounting only the incremental seats above each threshold.

Most Trello Power-Ups haven't solved this yet. The majority charge flat rates regardless of team size, and those offering multiple tiers tend to charge by features rather than seat count. If your Power-Up can serve teams of fifty or more, graduated pricing gives you a competitive advantage over publishers whose flat rates scare off larger teams.

The Hidden Complexity of Per-Seat Billing

Per-seat pricing sounds simple until you build it. Payment providers like Stripe handle the payment side—charging cards, calculating proration, managing subscription state—but they don't handle the per-seat part. Stripe doesn't know who's in a Trello workspace or whether a new member should get access. That's all on you.

You need to manage seat counts when users are added or removed, define your proration strategy, and build the entitlement logic that decides who gets access to paid features and what happens when a workspace exceeds its seat count. Each of these is solvable individually, but together they add up to a meaningful chunk of engineering work that diverts resources away from your product's features.

Why Salable Exists for Exactly This Problem

Salable picks up where Stripe leaves off. It handles seat management, entitlement checks, and access gating out of the box. You increment or decrement seats through the API, and Salable handles billing adjustments, proration, and entitlement state. Your Power-Up just asks "does this user have access?" and gets a clean yes-or-no answer.

The developers who scale their Power-Ups are the ones who spent their time on features that make users want to subscribe, and let purpose-built infrastructure handle the billing.

Finding Your Price

Start with a price you can defend in conversation. If a customer asks why your Power-Up costs $10 per seat, you should have a clear answer about its value relative to alternatives. If that answer doesn't come easily, your price or your messaging needs work.

Pricing isn't permanent. Starting slightly lower gives you room to raise prices as you add features and build a reputation. Starting too high creates resistance that's hard to overcome even after reductions. The goal is sustainable revenue that funds development while remaining accessible to teams that genuinely benefit from what you've built.
